  • 5 starsMrs Marie Adelman, 29/01/2014 - Love it, love it, love it!

    "I recently started using the REN products after being recommended them by my daughter in law and all I can say is WOW! I am over 50 with all the usual skin problems of a lady of a certain age and I purchased the Anti-Aging Kit which came with a sample of this product. As soon as I finished the sample I went straight back on the website and bought the bottle. I’ve only been using the kit for 3 weeks and I have noticed a huge difference in my skin already. I have used way more expensive products on my face and they have not given me the same results. I am now officially addicted to REN!"

  • 5 starsMiss V Viv, 20/11/2013 - Natural + Works = Winner

    "I have been using an expensive anti aging serum (ANR by Estee Lauder) for the past few years, until it stopped helping my skin. I started noticing dullness and larger pores developing over the past year. Since REN products were naturally sourced with no harmful chemical preservatives, I wanted to give it a try. Since using this concentrate, my skin has a dewy look with smaller pores and my hyperpigmented marks (acne) are slowly but surely fading away. I am beyond excited. Thank you, REN. I just ordered the Radiance Perfection Serum to add to my regime."

  • 5 starsMiss Leigh Moran, 29/06/2013 - I'm addicted

    "Absolutely love this product! It makes my skin so smooth and I have noticed a huge difference to blemish scars. It has made my face look a lot brighter and clearer! I use it every other night and its not to harsh on my sensitive skin! It's like waking up with new skin each time! Thanks REN!! It was my first purchase with you but it certainly won't be my last! Thinking of trying your cleansing balm next but waiting for it to change to the pot container! Any idea how soon that will be? Thanks!"

  • 5 starsMs Elysabeth Faslund, 01/03/2013 - Not a paid-for advertisement...

    "This is an incredible product, even men have complimented me on my complexion, of all things!Keep up the good work, Ren.Just wish there was a way to turbo-brighten my facial skin."

  • 5 starsAnonymous, 07/01/2013 - Love it!

    "Love this stuff, I apply it every few nights and it makes my skin so soft and really bright and healthy for a day or two after. You don't need much so I can see the bottle going a long way. Think it helps keep blemishes at bay too. Not as strong as other Glycolic treatments but that makes me like it more as I don't like to use treatments that are too harsh on my skin. Pipette is a bit awkward though, a pump would be more convenient."

  • 5 starsAnonymous, 26/11/2012 - Brilliant product for brilliant skin

    "Hi,I am Asian with sensitive skin. I am normally a little bit cautious of using non-Asian products and been sticking to SK-II water for a few months until I stumbled across this product at Helsinki airport duty-free. I gave it a go and I couldn't believe what it does to my skin. It's glowing, it's tight, the pores are refining and people been asking me what I've done to my face.Thanks and I just made it my 'favourite product for life'."

  • 1 starsAnonymous, 18/09/2012 - Meh.

    "When I read the reviews and claims on this product, I REALLY wanted to like it. In that vein I made the full commitment and went for the mask, as well. I've used the mask twice (one week apart) and the serum every night on clean skin for two weeks. My pores are just as clogged as ever, my texture as uneven, and my "radiance" just as blah. Neither product made my face tingle in the slightest but, so maybe I need something stronger? My skin is AHA and glycolic acid naive, so I was hoping for even a tiny bit of response. Unfortunately these are two Ren products that just didn't work for me at all."

  • 5 starsMiss phoenix JAMES, 19/08/2012 - hi

    "I was wondering if i could use this but im already using the glycolactic mask? thanks"

    REN replied :

    Yes, you can use both products. Please contact our product advisors for a tailored skincare routine at

  • 5 starsAnonymous, 16/06/2012 - Fragrance?

    "I noticed on the ingredients list "fragrance/parfume" is listed. However, I thought your products are fragrance free. Are only some of the fragrance free?"

    REN replied :

    Our products are not fragrance free. We use only 100% natural fragrance in all of our products. REN fragrances are made up of a blend of essential oils and plant extracts.

    "I love this product, but I'm a little confused how to use it. I keep reading to use it for a week and then to stop for 2 weeks. But I've been using it for a couple of weeks non stop since I couldn't find any indications on the product box. Can you help me?"

    REN replied :

    Thanks for your feedback! Our Resurfacing AHA Concentrate can be used in two different ways:

    As a booster, applying it every other day onto cleansed skin at night.
    Alternatively you can use it as a treatment applying it every night for a week onto cleansed skin and then giving a break of 2 weeks before reapplying again for another week and so on… This will complete the skin exfoliation process and leave it ready to renew itself over the next 14 days.

  • 5 starsAnonymous, 21/04/2012 - Wow!

    "I love this product! It leaves my skin smooth and glowing! I use the whole radiance line now. I'm extremely happy with the outcome and would advise all to try this."

  • 5 starsAnonymous, 28/01/2012 - Great Stuff!

    "Making a nice improvement to my skin. Just wondered when you say to apply one pipette is that a pipette full to the top or just a drop? Never quite sure how much I should be using?"

    REN replied :

    When you have filled the pipette it is 'half full' and this should be close to the right amount. Some people like to include the neck and decollete as well so it is hard to tell how much is needed exactly.

  • 5 starsAnonymous, 29/12/2011 - Amazing

    "From the first use, i noticed a difference! absolutely loved it; it made my skin smooth, so soft and helped with spots too. But I wasn't sure what to put on top, as i don't have the other radiance serum? Also whether to use toner underneath?"

    REN replied :

    You can use your normal moisturiser or night cream on top and there's no need to add a toner underneath. Thanks, REN

    "This is fantastic! I use it alongside the Radiance Mask and have had quite a few comments about how radiant my skin looks."
